c++: Fix [[deprecated]] and implicit operator==. [PR97358]
Trying to diagnose the problem with an implicit copy function breaks if the
function isn't actually a copy function.
gcc/cp/ChangeLog:
PR c++/95844
* decl.c (copy_fn_p): Return false for a function that is neither a
constructor nor an assignment operator.
(move_signature_fn_p): Likewise.
gcc/testsuite/ChangeLog:
PR c++/95844
* g++.dg/cpp2a/spaceship-eq10.C: New test.
